Overview
- A viral, unproven claim linking a Santa Clara electrical substation to the 49ers’ soft‑tissue injuries drew fresh attention as the Super Bowl comes to Levi’s Stadium.
- General manager John Lynch said the club will look into the issue after a season of high‑profile injuries, even as the NFL’s chief medical officer has downplayed a risk.
- The league says it has found no clear evidence supporting the theory and remains open to data, and the World Health Organization reports no established harm from typical low‑frequency EMF exposure.
- Owner Jed York rejected the premise, noting decades of practices next to the site and saying the idea can be debunked.
- Players offered mixed views: Christian McCaffrey and Brock Purdy expressed uncertainty, Fred Warner said more research may be warranted, Kendrick Bourne said he “kind of” believes it, and George Kittle said athletes want answers if anything could make them even 1% worse.
